Background

Edible oils play a vital role in our daily life, which provide human beings with energy, essential fatty acids and nutrients. The quality of edible oils can be dependent on the quality of the oilseeds they originate from, and their adulteration during processing. In recent years, near infrared spectroscopy was widely used in the rapid assessment of quality of oilseeds and edible oils. However, to the best of our knowledge, a comprehensive review on near infrared spectroscopy for the quality of oilseeds remains to be published.

Scope and approach

The applications of near infrared spectroscopy in the quality of oilseeds and edible oils have been emphasized in this review. This article briefly summarizes the basic knowledge of near infrared spectroscopy. In addition, we highlight the application of this technique on the detection of physicochemical properties and quality, specific nutrient components, authentication, and geographical origin traceability of oilseeds and edible oils. Moreover, the application of near infrared hyperspectral imaging technology in oilseeds has been addressed.

Key findings and conclusions: Near infrared spectroscopy possesses the advantages of rapid, green and low-cost analysis. Meanwhile, it is also a nondestructive method and therefore suitable to quality analysis of oilseeds in agricultural sciences. It can be used to detect macro nutrients in oilseeds and edible oils by combining NIR and advanced chemometrics. In the future, NIR could be applied in the rapid detection and online detection of hazardous substances and nutrients in oilseeds by developing the new instrument and chemometric methods.

近红外光谱方法在油料和食用油非破坏性质量分析中的应用

背景

食用油在我们的日常生活中起着至关重要的作用，为人类提供能量，必需脂肪酸和营养。食用油的质量可能取决于其来源的油料种子的质量及其在加工过程中的掺假。近年来，近红外光谱被广泛用于油籽和食用油质量的快速评估中。然而，据我们所知，关于油籽质量的近红外光谱的全面综述仍有待发表。

范围和方法

这篇综述强调了近红外光谱技术在油料和食用油质量中的应用。本文简要总结了近红外光谱的基本知识。此外，我们重点介绍了该技术在检测油料和食用油的理化性质和质量，特定营养成分，鉴定以及地理来源可追溯性方面的应用。此外，已经解决了近红外高光谱成像技术在油料种子中的应用。

主要发现和结论：近红外光谱法具有快速，绿色和低成本分析的优点。同时，它也是一种非破坏性方法，因此适用于农业科学中油料种子的质量分析。结合近红外和先进的化学计量学，可用于检测油料和食用油中的大量营养素。未来，通过开发新的仪器和化学计量学方法，NIR可以用于油料种子中有害物质和营养物质的快速检测和在线检测。
